Weather in September
Temperature
The transition into September subtly indicates a reduction in the average high-temperature, down to a moderately hot 81.7°F (27.6°C) from August's tropical 87.6°F (30.9°C). An average nighttime temperature of 62.8°F (17.1°C) is observed during September.Heat index
The heat index value during September is appraised at a tropical 86°F (30°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
